Met Office Forecast
South West England
Cloudy and wet, but some sunny spells in the afternoon.
Cloudy skies and persistent rain from early morning, spreading east across the region. This rain starts clearing in the afternoon, becoming drier with scattered showers and sunny spells in most areas. Strong and gusty winds, calming down in the afternoon. Maximum Temperature 16C.
Scattered showers, perhaps thundery in coastal areas, continue overnight interspersed with clear spells for most areas overnight. Generally light winds. Minimum Temperature 6C.
Further scattered showers across the region throughout the day. Showers locally heavy with a risk of hail and thunder. Some sunshine to be had outside the showers. Maximum Temperature 15C.
Outlook for Friday to Sunday:
Increasingly windy with persistent rain developing through Friday. Some outbreaks of rain on Saturday but also a few sunny intervals before returning to more prolonged rain on Sunday. Often windy.
Day 6-7 and Week 2:
An unsettled picture is likely for this period, with all parts of the country seeing showery spells as well periods of more prolonged rainfall at times. However, southern and western areas are expected to see the worst of these conditions with the most frequent and heaviest rainfall. Drier and calmer conditions could be seen at times, but likely only for short interludes. It will often be windy during this period, with a risk of gales at times, particularly along western and southwestern coasts. Overall, it is likely to feel rather cold as temperatures look set to be around average or below. During any of the brief calmer interludes overnight frost is also possible in the North.
Week 3 and 4:
A potential change in the weather is signalled around the middle of October. Whilst further rain and strong winds are likely at times, spells of fine and dry weather could become more widespread and long-lived. At night, these calmer conditions would allow frost and fog to form more readily. At this time of year, there is potential for fog to linger well into the daytime. Overall, temperatures probably recovering close to the seasonal average for mid-October.
Met Office : South West England : 2020-09-30T01:38:32
Daylight : Wiltshire
Day length is dusk to dawn. Times will vary a little if there is a hill on the horizon.
It should still be light enough to read at dawn and dusk, so there will be enough light for walking even earlier (later).
Moonlight : Wiltshire
- The moon's phase or fracillum (percentage of the moon illuminated) doesn't vary much with location.
- A full moon is not just bigger, its much brighter. A half moon ('50%') give less than 5% of the illumination of a full moon. You can walk with a half moon if its high in the sky (after dusk for a growing moon, before dawn for a shrinking moon).
- Sky glow (light reflected by air or clouds) from nearby cities, and especially snow on the ground also effect light levels.
- Times will vary a few minutes, as (i) these figures are for the centre of the county the walk is in, (ii) if there are hills on the horizon, and (iii) if you are on a hill
- Of course, you need a cloudless night as well!
